Hi, all!
Is it possible to invert the coordinate system of a page? I mean, the
measurement of a page become at its lower-left corner. It's possible to change
this to the up-left corner instead?
Alessandro Antonello

And while we're at it, is it possible to offset the origin of the coordinate
system at all?
Real example: I'm designing a board game and to make things easier I'd like
all measurements to start at the center of the board at design-time and or
3,5 cm from the top/left edge of the page when certain tiles are to be
aligned to a grid specified by the print house.
Of course I can move around the artwork in relation to the origin but I can
not as easily select all the guides and move them with the artwork and so,
the best thing would be to be able to move the page origin.
With kind regs,
Jimmy Volatile

sorry, not at the moment, but is a known issue/missing feature according
to the comments to these bug reports:
Inverted ruler co-ordinate system

Bottom/up coordinate system

As I could see in that posts, the coordinate system will cannot be changed in
the next release of Inkscape. Maybe developers are taking this too much deep
on changes that must be made to accomplish this feature. In the past century,
Corel DRAW default coordinate system was bottom/left. But we could change it
to top/left easily. The changes was made only in the interface. Internally
and in the files the measurements still was written in the default coordinate.
So, IMHO, changing the coordinate in the drawing canvas could be just an
adjustment in the interface of the software. Internally, Inkscape could still
work in its default coordinate system, until the "deep" changes can be made to
keep the SVG file format according to the standard.

The irony is that the SVG standard uses upper-left as 0,0 in it's
coordinate system. The inkscape devels chose to make bottom-left the
GUI coordinate system, and convert everything in the XML file.

Actually we inherited that from sodipodi, and have never got round to
changing it.

Didn't realize that, John.
How embedded is that mapping? I browsed through the source code in
SVN and couldn't locate a single base transform applied to everything
when moving from the XML schema and the application. (Though I'll
admit it wasn't a thorough search...)
